I was always told that this was an earthing cable Thoughts???

I’m an electrician and this is done because if the building is hit with lightning it will be grounded straight to the Earth.

Yep, that's what I've always been told

Ground wire for a lighting rod. In Teslas diagrams for the radiant energy, the upper portion had an enormous surface area. Maybe if the fella makes a video of a giant 18th century ferrous balloon and a wire?

Well that’s embarrassing showing your lack of education to the massives. They teach electrical circuits from a very young age in schools now! My 2 bedroom semi detached house has this fitted in case of lightning strikes.

You didn't read the title. Did you 🤔

Lightening rod earth,

That's a lightning rod dummy

It’s made to power the flux capacitor with a lightning strike 😎

someone skipped class.

Stick a meter on that wire to prove power. It’s a lightning ground. 🥸
